A high-protein diet for the child with major burns is ordered to:
 
  a. Promote growth.
  b. Improve appetite.
  c. Diminish risks of stress-induced hyperglycemia.
  d. Avoid protein breakdown.

Question 2

Which physiologic change causes the edema formation that occurs with burns?
 
  a. Vasoconstriction
  b. Decreased capillary permeability
  c. Increased capillary permeability
  d. Decreased hydrostatic pressure within capillaries

Answer to Question 1

ANS: D
The diet must provide sufficient calories to meet the increased metabolic needs and enough protein to avoid protein breakdown. Healing, not growth, is the primary consideration. Many children have poor appetites, and supplementation will be necessary. Hypoglycemia, not hyperglycemia, can occur from the stress of burn injury because the liver glycogen stores are rapidly depleted.

Answer to Question 2

ANS: C
With a major burn, an increase in capillary permeability occurs, allowing plasma proteins, fluids, and electrolytes to be lost. Maximal edema in a small wound occurs about 8 to 12 hours after injury. In larger injuries, the maximal edema may not occur until 18 to 24 hours after injury. Vasoconstriction, decreased capillary permeability, and decreased hydrostatic pressure within capillaries are not physiologic mechanisms for edema formation in burn patients.
